The normal temperature compressive strength is 70~260MPa. It is mainly used for hot blast furnace top, blast furnace stack and bottom, glass furnace regenerative chamber ceramic sintering kiln, blind corner lining of petroleum cracking system, etc

KSINO is committed into independent R&D and innovation of high-temperature kiln products, as well as providing high-quality products for high-temperature kilns. In terms of circulating fluidized bed boiler, vaporizer, fluidized bed furnace, garbage incinerator, rotary kiln and other types of furnace structures, it has advanced optimization concepts. KSINO has accumulated rich experience in furnace construction, design, improvement, construction, drying and insulation, and formed a service chain throughout the whole life cycle of high-temperature kilns. KSINO mainly produces heavy shaped, amorphous, light shaped, amorphous furnace refractories, refractory bricks, etc. The products have been widely used in glass, power, metallurgy, non-ferrous, petrochemical, building materials, rotary kilns and other fields. 

Japan JIS industrial standard thermal insulation brick has light weight, low iron content, low refiring shrinkage, low thermal conductivity, low heat capacity, low impurity content, high strength, and has good thermal shock resistance and atmospheric corrosion resistance, high dimensional accuracy Excellent characteristics. Products are widely used in industrial furnace hot surface lining, such as annealing furnace, carbonization furnace, tempering furnace, oil refining heating furnace, cracking furnace, roller furnace, tunnel furnace and other industrial furnace backing insulation materials.

This series of products is suitable for the temperature range of 900℃1500℃.
